Among foodborne bacterial pathogens, Staphylococcus aureus and Pseudomonas aeruginosa are of extraordinary significance which drive reasons of food and beverage poisoning in numerous cases. Today, PCR has been widely used to examine the presence of different foodborne pathogens. However, PCR requires specialized equipment and skillful personnel which limit its application in the field. Recently, there is an emerging of isothermal PCR methods in which the reactions occur at low and constant temperature, allowing their application in restricted-resource settings. In this work, multiplex Recombinase Polymerase Amplification (RPA) was used to simultaneously detect S. aureus and P. aeruginosa with high sensitivity and specificity. The limit detection of multiplex RPA was 10 and 30 fg/reaction of genomic DNAs of S. aureus and P. aeruginosa, respectively. Besides, the reaction time was reduced to only 25 minutes with a low incubation temperature of 39 °C. Markedly, multiplex RPA reactions succeeded to directly detect as low as 1 and 5 CFU/reaction of S. aureus and P. aeruginosa cells, respectively without the requirement of extracting DNA genome. Moreover, the multiplex RPA reliably detected the two foodborne bacteria in milk, fruit juice and bottled water samples. In general, the direct multiplex RPA described in this study is a rapid, simple, sensitive and efficient alternative tool that could be used to detect the presence of S. aureus and P. aeruginosa without the necessity of costly devices and high-trained staff.","PeriodicalId":19025,"journal":{"name":"Molecular Biology Research Communications","volume":"11 1","pages":"1 - 10"},"PeriodicalIF":1.6,"publicationDate":"2021-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49483745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2013, the Global Aquaculture Alliance (GAA) estimated shrimp farming decline in Asia accounted for 1-billion US dollar lost. Currently, diagnosis using PCR method does not meet the demand of <i>in situ</i> detection, which is based on antigen-antibody interaction, has not been developed yet. In this present study, we proceeded to create the toxin and its antibody for lateral flow development. First, recombinant toxin ToxA was generated by gene manipulation. After that, purified ToxA was used to immunize rabbits. Finally, antisera from rabbits and protein-A purified antibodies were evaluated for titer, specificity, and detection threshold. Results showed that recombinant ToxA was overexpressed in soluble fraction at 37<sup>o</sup>C with 1mM IPTG. Purification by affinity chromatography was able to isolate recombinant ToxA with the purity up to 94.49%. In ELISA experiment, the immunized antisera reached a titer of up to 1/5,210,000 with 1µg/ml of antigen, and detection threshold was 100ng recombinant toxin. After purification, the detection threshold of purified polyclonal antibodies was 25ng toxin per dot. These results laid a groundwork for the development of AHPND detection kit based on antigen - antibody interactions.</p>","PeriodicalId":19025,"journal":{"name":"Molecular Biology Research Communications","volume":"10 1","pages":"23-32"},"PeriodicalIF":1.6,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7936389/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25447460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
